In a long line of stellar games, this one takes it to another level. Everything about the game stuck my as perfect. Each weapon is an absolute blast, combat is chaotic, but always fair and extremely well paced.
The dialogue is witty and laugh out loud funny in certain moments. The characters are probably what stand out the most. All of them are incredibly charming and bring life to an already vibrant world. The story is endearing and engaging.
I can't really think of anything negative about the game. I encountered a couple technical glitches here and there, I probably lost a total of five minutes of progress because I fell through the earth a couple times.
Buy this game. I think all of the main R&C titles have been commercially successful, but I hope this one tops the charts because it deserves to. Hopefully they'll make another one.
